Option 4: Growing Strength of Regional Parties - COALITION GOVERNMENT

Coalition governments:

Following the elections of 1989, a notable shift towards coalition politics became prominent in India's political landscape. Since that juncture, the country has seen eleven different governments at the national level. These administrations have predominantly taken the form of either coalition governments or minority governments that receive support from other parties, without formally joining the government. This marked a new phase in Indian politics, where the formation of any government hinged on the participation or backing of various regional parties. As the coalition governments were formed in many states with the help of support of the regional parties. This led to the growing strength of regional parties from the 1990s.
